SID Shows the current SID, the recommended SID for this technique.
The alert icon indicates that the SID is not at the recommended
position. A checkmark indicates that the current SID matches the
recommended SID.
NOTE: Exposure may not be inhibited if the current SID is not the
recommended SID.
Ion Chamber:
(AEC mode only)
If in AEC mode, selects the ions chambers to use.
NOTE: When in AEC mode, at least one ion chamber must be
selected. Any combination of chambers is allowed.
NOTE: When in AEC mode, the body part must cover the selected
ion chambers in order to achieve the proper exposure.
Refer to Chapter 7:
Automatic Exposure Control (AEC) for more
information about AEC.
kV Adjusts the kV.
The up/down buttons on the right of the field adjust the kV by one
unit.
The buttons on the left of the field adjust the kV by 5 units.
The kVp selection range is 40-150, in1 kVp increments.
mA Adjusts the mA.
The mA selection is in Renard steps. The available selections are:
10, 12.5, 16, 20, 25, 32, 40, 50, 64, 80, 100, 125, 160, 200, 250, 320,
400, 500, 640.
NOTE: Not all mA and mAs selections are available at all kV settings.
mAs If in FIXED mode, adjusts the mAs.
The mAs selection is in Renard steps. The available selections are:
0.1, 0.12, 0.16, 0.20, 0.25, 0.32, 0.40, 0.50, 0.64, 0.80, 1.0, 1.25, 1.6,
2.0, 2.5, 3.2, 4.0, 5.0, 6.4, 8.0, 10.0, 12.5, 16.0, 20.0, 25.0, 32.0, 40.0,

320.0, 400.0, 500.0, 512.0.
NOTE: Not all mAs selections are available at all kV settings.
If in AEC mode, shows the calculated mAs for the current kV and
mA after exposure.
